Abstract[English]
Disclosed is a method for implementing a thermodynamic cycle for an elastocaloric material. The method includes increasing a stress applied on the elastocaloric material, till the stress reaches a desired stress value or the elastocaloric material transitions from austenite to martensite form, decreasing a temperature of the elastocaloric material from high to low value, and decreasing a stress of the elastocaloric material to maintain a constant volume fraction of corresponding martensite form during temperature decrease, decreasing the stress of the elastocaloric material, till the stress reaches a minimum stress value or the elastocaloric material transitions from martensite to austenite form, and increasing the temperature of the elastocaloric material from low to high value, and increasing the stress of the elastocaloric material to maintain a constant volume fraction of corresponding martensite form during temperature increase.[French]
L'invention concerne un procédé de mise en œuvre d'un cycle thermodynamique pour un matériau élastocalorique. Le procédé comprend l'augmentation d'une contrainte appliquée sur le matériau élastocalorique, jusqu'à ce que la contrainte atteint une valeur de contrainte souhaitée ou le matériau élastocalorique passe de la forme austénite à celle martensitique, la diminution d'une température du matériau élastocalorique d'une valeur élevée à basse, et la diminution d'une contrainte du matériau élastocalorique pour maintenir une fraction volumique constante de la forme martensitique correspondante pendant la diminution de température, la diminution de la contrainte du matériau élastocalorique, jusqu'à ce que la contrainte atteint une valeur de contrainte minimale ou le matériau élastocalorique passe de la forme martensite à celle austénitique, et l'augmentation de la température du matériau élastocalorique d'une valeur basse à élevée, et l'augmentation de la contrainte du matériau élastocalorique pour maintenir une fraction volumique constante de la forme martensitique correspondante pendant l'augmentation de température.
